You will need to talk with your ‘Trunk Provider’ for that
It’s inappropriate to use an exten of _. in from-internal or from-internal-custom. Look at this post to see a supported way to add dialplan for this use case: Hooking for fun and income
Hi Dicko,
Thanks for you reply.
I’m not using any trunk here. Both the caller and the callee are local extensions…
So are you telling me that DENOISE only works fro analog trunks? That’s the reason the call disconnects?
Is there any other function or module (even if commercial) that can be used to improve/clean inbound audio you know of?
Thanks a lot!
“Clean inbound audio” is doing a lot of work here. If you are SIP all the way through and are not using analog lines at your PBX what audio is there to clean outside of getting better microphone and headset?
‘bad’ audio on a digital signal will normally be caused by missing, delayed or out of order packets, It is not ‘noise’ per se though, so you need to direct your attention to correcting your network.
